HORSE SHOE-CALK.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed. August 27, 1907. Serial No. 390,385.

T o all whom it may concern:

Be it known that I, FRANK B. GARDNER, residing at Lima, in the county ofAllen and State of Ohio, have invented certain new and usefulImprovements in Horseshoe-Oalks, of which the following is aspecification.

My present invention seeks to provide a new and improved construction ofcushion horse-shoe calks, and it more particularly relates to that typeof heel calks shown in my Patent No. 769,071 granted August 30, 1904,and it comprehends certain improved features of construction, especiallya means for connecting the calk and the cushion member to the shoe insuch manner that a positive holding of the outer end of the calk ltndthe cushion against the shoe is provided In its more complete nature, myinvention also embodies certain details of construction and combinationof the several parts, and

articularly the means for detachably interocking the calk with the shoeends and whereby the cushion member when worn, may be readily removedand a new cushion piece substituted therefor, all of which will ehereinafter fully described in detail and pointed out specifically inthe appended claims and illustrated in the accompanying drawings, inwhich,-

Figure 1 is a perspective view of a horseshoe with my im rovementsapplied. Fig. 2 is a longitudina section of one heel end of the shoe,taken on the line 2-2 on Fig. 1. F-ig. 3 is a perspective view of theheel end of the shoe without the calk and cushion members. Fig. 4 is adetail view of one of the heel calk pieces. Fig. 5 is a detail view ofone of the cushion members. Fig. 6 is a cross section on the line 6-6 ofFig. 2. Figs. 7 and 8 are detail views hereinafter referred to.

The horse-shoe 5, which may be of the ordinary flat shoe type in mypresent construction or invention, has its heel ends formed with asocket 50 having a longitudinally extended contracted entrant portion 51whereby to form opposing locking flanges 52, for cooperating with aheaded stud integrally formed with a calk piece 6, as clearly shown inFig. 2.

In my (present construction, the calk 6 has a forwar ly extended flatportion or tongue 61 that is disposed inta plane above the calk portionproper whereby to form an off-set between the shoe and calk to providethe space for receiving the cushion block 9 of rubber or other yieldingmaterial. y

The block 9 has a wedge shape to fill the wedge shape space which isprovided for by having the calk member inclined downwardly from thefront to the rear end, and the said cushion block 9 also has an aperture90 of less diameter than the head of the stud 60, it being understoodthat in applying the cushion block, its aperture 90 expands sufficientlyto readily slip over the head 60.

The front end of the tongue 61, in practice, is secured to the shoe end5 in any suitable manner. For example, it may be detachably secured by ascrew 8 that extends down through the shoe end, through an aperture 63vin the tongue and made fast by a nut, as shown in Figs. 1 and 2, or itmay be secured by passing the screw up through aperture 63 through theshoe end and securing same by the nut 82 countersunk in the upper faceof the shoe end 5, as shown in Fig. 7, or it may be riveted to the saidshoe end, as shown in Fig. 8. To prevent the cushion 9 being crowdedrearwardly over the end of the calk, the said calk end has one (or more)spurs 65 near its outer end that projects up into the cushion, as shownin Fig. 2.

By reason of constructing the several parts as described, to fit thecalks onto the shoe ends, it is only necessary to pass the heads 62 ofthe studs into the circular or wide entrant portion of the sockets inthe shoe heels, and then slip the calk forward in the longitudinaldirection of the shoe end to bring the head 62 under the lock flanges ofthe contracted entrant extension of the socket and thereby positivelylock the rear end of the calk to the shoe and prevent the same fromwabbling laterally or longitudinally. After the calk has been thusiittedon the shoe, the rear end of member 61 is fixedly secured to the shoe.

From the foregoing, taken in connection with the drawings, theadvantages of my invention will be readily understood.

By reason of the calk being connected to the shoe in the manner stated,the cushion, when worn, can be replaced by removing the calk andsubstituting a new cushion for the old one and replacing the calk andsecuring it back on the shoe.

The arrangement of parts is such that no especial construction of shoeis necessary, since the calk device can be readily fitted to ent is:

1.y The combination of a horse-shoe having sockets in the heel portionthereof, a calli plate detachably secured at its front end to each heelportion, an off-set at its rear Vend therefrom, a cushion between theshoe and off-set portion of the plate, a stud on each plate, forextending through the cushion, the said studs having head portions forextending into and detachably interlocking with the sockets in the shoeheel portions, as set forth. Q

2. The combination with the heel portion of a horse-shoe, said portionhaving an elongated socket extending lengthwise thereof and having aportion of its entrant end oontracted whereby to form opposing lockingflanges and having an aperture in advance ol' the contracted portion ofthe socket; of a calk having a forwardly projected tongue member and aheaded stud adapted to slip into the socket in the heel portion and tobe moved into an interlocked engagementwith the locking edges thereof, ayielding cushion member, apertured to slip over the said headed stud,and means for connecting the front end of the calk to the shoe heelportion, all being arranged substantially as shown and described.
